Definitions

  • the present invention relates generally to bottem driven rotary cutting mechanisms of the type as shown in e.g. FR-A-1.480.616, and more particularly, to crop lifters for the rotatable disc cutter members of such rotary cutting mechanisms.
  • the present invention is particularly useful when the rotary cutting mechanism according to the invention is incorporated in a mower-conditioner.
  • Mower-conditioners have been provided for a number of years to sever standing crop material and convey the severed crop material rearwardly into a conditioning mechanism without depositing the severed crop upon the ground.
  • a disc mower-conditioner utilizes a disc cutterbar having a number of transversely spaced disc cutter members rotatable to sever standing crop material by an impact action.
  • a conditioning mechanism is mounted rearwardly of the disc cutterbar to receive the severed crop material directly from the disc cutter members without the need of an intermediate crop conveying mechanism.
  • the rapid rotation of the disc cutter members creates a high rate of wear under abrasive crop and/or soil conditions, subjecting the hardware detachably connecting the knives to the disc cutter members to a great amount of wear, requiring frequent replacement of the knife fastening hardware.
  • a disc cutter member of a rotary cutting mechanism hampered with these drawbacks is shown in FR-A-2.072.365.
  • This cutter member conventionally comprises a raised, generally central portion which is fully exposed and a lower, peripheral portion to which the knives are connected.
  • Each individual knife is connected to the upper side of the lower peripheral portion of the cutter member and a two-part shielding means, consisting of an inclined lead-in surface and a shielding plate parallel to the lower peripheral portion, is welded to said lower peripheral portion in overlapping relationship with as well the mounting portion of each individual knife as the mounting hardware for each said knife.
  • the total height of these shielding means has been kept as small as is practically possible.
  • DE-A-2.222.415 shows a disc mower having crop divider means of a substantial height mounted on top of the outermost disc member for dividing freshly severed crop material from crop material which is still standing in the field.
  • a rotary cutting mechanism which, in operation, continuously lifts crop material away from the cutting zone immediately after being severed, thus preventing a build-up of severed crop material in front of the cutter members hindering the proper severing of further standing crop material on the one hand, while simultaneously protecting the knife fastening hardware from excessive wear on the other hand.
  • the cutting mechanism is incorporated in a disc mower-conditioner, it furthermore also is the objective to improve the feeding characteristics of severed crop material from the disc cutterbar to the rearwardly mounted conditioning mechanism without the utilization of an intermediate crop conveying mechanism.
  • a rotary cutting mechanism which includes at least one bottom driven disc cutter member having at least one knife detachably connected thereto; the or each said disc cutter member, in use, being supported adjacent the ground and rotated about a generally vertical axis for severing standing crop material by impact and comprising:
  • a disc mower-conditioner having a disc cutterbar with transversely spaced rotatable disc cutter members to sever standing crop material by an impact action and a rotatable conditioning mechanism mounted rearwardly of the cutterbar to receive and condition severed crop material and wherein each disc cutter member is of the type as specified hereabove.
  • the crop lifters thereof further also are operable, in this combination, to facilitate a feeding of severed crop material into the conditioning mechanism.
  • FIG. 1 a top plan view of a hay harvesting machine, commonly referred to as a disc mower-conditioner can be seen. Any left and right references are used as a matter of convenience and are determined by standing at the rear of the mower-conditioner and facing in the direction of forward travel.
  • the mower-conditioner 10 is shown in the form of a pull-type machine having a draft member 12 pivotably connected to the frame 14 of the machine 10.
  • Theframe 14 includes a main transverse support beam 15 to which are connected downwardly depending legs 17 mounting wheels 18 for mobilely supporting the machine 10 over the ground, as best seen in Fig. 2.
  • the mower-conditioner 10 includes a crop harvesting header 20 floatingly supported for movement over the ground and relative to the frame 14 by the counter balancing mechanism 22 and upper and lower links 23, 24 interconnecting the header 20 and the frame 14.
  • the header 20 is provided with a crop cutting mechanism 25, seen in the form of a disc cutterbar 26, such as a Kuhn three meter, six rotor rotary cutterbar, having a plurality of transversely spaced disc cutters 28 operable to sever standing crop material by an 1 impact action.
  • a conditioning mechanism 30 is mounted in the header 20 rearwardly of the cutting mechanism 25 to receive and condition crop material severed by the cutterbar 26.
  • the conditioning mechanism 30 includes a pair of cooperable, generally vertically spaced transverse conditioning rolls 32, 34 operable to condition severed crop material passing therebetween.
  • Each roll 32, 34 is rotatably supported between the header side sheets 21 such that the axis of rotation 33 of the upper conditioning roll 32 is spaced slightly forwardly of the axis of rotation 35 of the lower conditioning roll 34, so that thenip 37 formed therebetween is facing slightly downwardly toward the disc cutterbar 26.
  • the preferred embodiment of the conditioning roll construction shown in Figs. 1 and 2 is of the intermeshing lug design.
  • a conventional drive mechanism 39 provides a source of rotational power to both the disc cutterbar 26 and the conditioning mechanism 30.
  • each of the remaining interior disc cutters 28 will have a construction as shown in Figs. 3 and
  • Each disc member 40 of the interior disc cutters 28 includes a raised central portion 41 in which are formed recessed mounting holes 42 for connection of the disc 40 to a driving member (not shown) in a conventional manner.
  • the axis of rotation 43 of the disc member 40 is positioned in the center of the raised central portion 41.
  • the disc cutter member 40 also includes a lower peripheral portion 44 terminating in a peripheral edge 46 extending around the circumference of the oval shaped disc member 40.
  • Each disc member 40 is provided with a pair of diametrically opposed knives 45 detachably con- nectedto the peripheral portion 44 by fasteners 47. Upon rotation of the disc member 40, the knives 45 sever standing crop material by an impact action.
  • the disc member 40 also includes an intermediate sloped portion 48 interconnecting the raised central portion 41 and the lower peripheral portion 44.
  • a crop lifter 50 is shown in Figs. 3 and 4 as attached to the peripheral portion 44 of the disc member 40 adjacent to each knife 45 and in leading relationship thereto when viewed in the direction of rotation of the disc member 40, indicated by the arrow 49.
  • the crop lifter 50 is detachably connected to the disc member 40 by the knife fastener 47 and a second fastener 52 extending through an opening 53 in the intermediate sloped portion 48 of the disc member 40.
  • the crop lifter 50 includes a lower leading edge 54 and a raised trailing edge 56 interconnected by an inclined ramp portion 55.
  • a recessed connecting portion 57 is affixed to the trailing edge 56 to provide a means for connecting the lifter 50 to the disc member 40.
  • the connecting portion 57 is shaped to correspond to the peripheral and intermediate sloped portions 44, 48 of the disc member 40 to which the lifter 50 is attached.
  • the connecting portion 57 is recessed sufficiently below the trailing edge 56 to permit the connecting hardware 47, 52 to be protected behind the crop lifter 50.
  • the connecting portion 57 is provided with spacers 58 to facilitate a tight mounting connection of the lifter 50 onto the disc member 40.
  • the inclined ramp portion 55 is provided with an apron 59 extending circumferentially from the leading edge 54 to the trailing edge 56 and vertically from the inclined ramp portion 55 downwardly to the lower peripheral portion 44 of the disc member 40.
  • the purpose of the apron 59 is to lend rigidity and support to the inclined ramp portion 55 and to prevent a build up of debris between the lifter 50 and the disc member 40.
  • the height of the trailing edge 56 of the lifter 50 is in approximately the same plane as the height of the raised central portion 41 of the disc member 40.
  • the positioning of the lifter 50 in leading relationship to the corresponding knife 45 permits the lifter 50 to protect the mounting hardware 47 for the knife 45 from abrasive wear.
  • the inclined ramp portion 55 provides an aggressive lifting action to previously severed crop material to lift such material from the zone immediately trailing the cutting zone of the corresponding knife 45. This lifting action helps prevent severed crop material from passing beneath the conditioning mechanism 30 and also helps to feed the severed crop material into the nip 37 of the conditioning rolls 32, 34 to effect a conditioning thereof.
  • the lifter 50 will be subject to abrasive wear from the typical cutting conditions in which rotary cutter- bars are normally used.
  • the detachably connected lifter 50 can easily be replaced to extend the operative life of the more expensive disc member 40.
  • the replacement of the lifter 50 can be accomplished at a significant cost saving when compared to a replacement of the entire disc member 40.
  • the crop lifter 60 is somewhat similar to the embodiment shown in Figs. 3-9.
  • the lifter 60 includes a leading edge 62, a trailing edge 64, and an inclined ramp 65 interconnecting the leading and trailing edges 62, 64.
  • a recessed connecting portion 66 with appropriate spacers 67 detachably connects the trailing edge 64 of the lifter 60 to the lower and intermediate sloped portions 44, 48 of the disc member 40 with the connecting hardware 47, 52.
  • the leading edge 62 of the lifter 60 is provided with a restraining pin 68 engageable with a corresponding opening appropriately positioned within the intermediate sloped portion 48. The restraining pin 68 restricts the movement of the leading edge 62 and helps locate the position of the lifter 60 relative to peripheral edge 46 of the disc member 40.
  • the inclined ramp 65 extends over substantially an entire quadrant of the peripheral portion 44 of the disc member 40, such that the orientation of the leading edge 62 is disposed at approximately 90 degrees to the orientation of the trailing edge 64.
  • the width of the inclined ramp 65 increases from the leading edge 62 to the trailing edge 64, creating a pork-chop-like shape. This longer, gradually sloping ramp 65 provides a more gradual lifting of the severed crop material, to create a less aggressive crop lifting action than will be obtained from the crop lifter 50 described above.
  • peripheral apron 69 extending circumferentially from the leading edge 62 to the trailing edge 64 and vertically between the inclined ramp 65 and the peripheral edge 46 of the disc cutter lends support to the inclined ramp 65 and prevents the entrance of crop material and/or other debris into the cavity formed between the inclined ramp 65 and the disc member 40.
  • the highest point of the lifter 60 is at the trailing edge 64, which preferably should extend to substantially the same plane as the raised central portion 41.
  • the connecting portion 66 is recessed sufficiently to permit the raised trailing edge 64 to protect the connecting hardware 47, 52.
